7. Reference Information - Network Traffic

When AudioFetch Express is used in Access Point Mode, the built-in Wi-Fi is
compatible with all required network traffic to/from connected mobile devices.
However when Client Mode is used to connect to a pre-existing network, it is
important to ensure that the required network traffic is able to flow between
AudioFetch Express and mobile devices running the AudioFetch App. In some
cases minor adjustments to network settings may be necessary, this
information is provided to help IT personnel determine and make the required
adjustments.
